Yep! That's for sure! :-) There are a lot of Honda and Mitsubishi
econo-boxes out there turning easy 9's. Its amazing how much power
you can get out of one of those small displacement 4-bangers with
nitrous and a turbocharger! =) (600-800HP out of a couple of liters
is not unheard of)

As far as I know (I could be wrong) nitrous, blowers, and turbos all
include fuel regulation as a part of the system to keep the fuel/air ratio
just where you want it. Otherwise, they just plain wouldn't work. The
additional air doesn't do much unless you supply additional fuel to burn
with it... (This is a nice thing about nitrous; since its only on at
WOT, you don't have to worry about the fuel/air ratio throughout the
entire powerband.)

You're right, of course. Any of these power increasing techniques will
increase the energy of the explosion, since that's how they generate the
additional power. A by-product of this will always be heat. However,
a turbocharger or a supercharger simply supplies more oxygen allowing
more fuel to be burned, and at the same time, they generate heat on
their own. (Sometimes, a LOT of heat!) Most turbochargers require an
intercooler. Nitrous, on the other hand, increases the amount of oxygen,
but ALSO cools the combustion chamber as a result of changing state from
a liquid to a gas! This state change requires energy, and the energy it
uses is heat from the combustion chamber. So, you increase oxygen like a
blower or turbo, but you also cool the chamber. The actual energy and
heat from the added power will be the same, but the nitrous takes
away some of that heat as it is injected into the chamber during the next
cycle. How much heat it absorbs, I don't know, but whatever it is, its
more than a blower or a turbo, since they offer no cooling effect.
(I think I read that it cools the chamber by 40-60 degrees F, but don't
quote me on that, I don't remember the exact numbers. I will look them
up if anyone is interested.)

A lot of this depends on the amount of nitrous you're injecting, and
the quality of the system. Most street nitrous systems keep things at a
safe level; they're designed specifically for stock or mildly modified
engines. They also have systems which are designed for engines built
especially for nitrous, but those systems are not recommended on a stock
engine. However, if we assume we're at a fairly high level where it is
putting some wear on the engine, the same could be said of a supercharger
or turbocharger. At similar power increases, they'd have the same effect
on a stock engine.
